Richard Hammond journeys to discover the startling engineering connections behind the Troll A gas platform, the largest object ever moved by man across the surface of the Earth. During his voyage, he reveals that Troll A owes its incredible design to a 19th-century French gardener, a 16th-century German mayor, an American architect and the dawn of the motor industry. Hidden in its DNA, he finds a crystal glass, a farm building, a racing car, a plant pot and nothing!
